[0002] Insulators are devices installed between conductors at different potentials or between conductors and ground potential components. They can withstand voltage and mechanical stress. Porcelain insulators need to be made into clay blanks first. After the clay blanks are dried in the shade and have a certain hardness, they can be glazed. After the glazing process, a drying device is needed to dry the glaze on the surface.

[0003] In order to speed up the processing of a large number of insulators, an assembly line method is generally used to spray glaze on the insulators. Since the insulators are moving on a conveyor belt, they are prone to collision and contact with the edge of the conveyor belt. The friction generated can easily wear the insulators. At the same time, the contact area between the insulator and the conveyor belt is prone to omission of spraying.

[0004] Therefore, it is necessary to propose a spraying and drying device and a processing method for a porcelain insulator glaze to solve the above problems. Summary of the invention

[0022] In the fourth step, the insulator body passes through the upper spraying assembly and the lower spraying rotating assembly in turn. The lower spraying rotating assembly rises to drive the insulator body to rise and rotate, and the lower surface and side surfaces are sprayed at the same time. After the spraying is completed, it is dried.

[0023] Technical effects and advantages of the present invention:

[0024] 1. In the actual operation of the invention, by starting the second motor, the second motor drives the two conveyor belts to transmit, thereby realizing the transportation of the placed insulator body. When the insulator body is placed on the support block, it can have an anti-slip effect to prevent the insulator body from sliding on the conveyor belt during movement. At the same time, it can reduce the contact area of ​​the bottom end of the insulator body and reduce the sticky area generated after spraying. Since there is a gap between the two conveyor belts, the friction contact with the bottom end of the insulator body is reduced without affecting transportation, and at the same time, there is space at the bottom for subsequent spraying.

[0025] 2. In the actual operation of the present invention, when the insulator body is placed on two conveyor belts for transportation, the L-shaped baffles can intercept both sides of the conveyor belts to prevent the insulator body from falling when it moves. At the same time, the L-shaped baffles can be used as wind ducts. The gases generated by the two air pumps are discharged from the corresponding wind troughs. The two wind troughs blow the insulator body relative to each other to form a balance, so that the insulator body can be in a centered position, avoiding contact friction between the side of the insulator body and the L-shaped baffles, which affects the surface smoothness of the insulator body, as well as the subsequent spraying and aesthetics.

[0026] 3. After the insulator body is sprayed, the wind force output by the wind trough can accelerate the drying and solidification speed of the glaze on the outside of the insulator body, while ensuring that the side of the insulator body after spraying will not contact and stick to the L-shaped baffle, causing incomplete glaze, and during the transportation process, the spraying and drying of the entire insulator body are completed. Compared with the prior art, which requires the use of a mechanical arm to repeatedly flip the insulator body for spraying, the present invention can reduce the repeated operation of the machine, reduce energy consumption, and has a lower cost of use.

[0027] 4. When in the spray box, after the fan is started, the wind is discharged from the air outlet at the bottom of the corresponding isolation plate to form a vertical downward wind curtain. When the unsprayed insulator body passes through the first air outlet, the dust on the surface can be removed to avoid bulges. When the insulator body between the two air outlets is sprayed with glaze by the upper spray assembly, the wind curtain generated by the two air outlets can isolate the glaze from splashing and play a blocking role. Compared with the traditional baffle blocking, it will not adhere to the baffle. At the same time, the effect of wind can directly make the excess glaze drop to the collection box at the bottom. When the insulator body with sprayed upper surface passes through the second air outlet, the effect of wind can accelerate the drying of the glaze.

[0028] 5. When the insulator body moves to the position of the lower spray rotating assembly, the second electric push rod rises, driving the fixed disk and the protruding end to extend upward until the protruding end touches the bottom end of the insulator body, supports the insulator body, and drives the insulator body to rise and separate from the support block. While the fixed disk rises, multiple nozzles are started to spray radial glaze upward, completing the spraying of the lower surface of the insulator body before contacting the bottom end of the insulator body.

[0029] 6. In addition, when the fixing plate rises, the hollow column will be inserted into the center hole opened on the insulator body, and the glaze can be discharged from the spray hole to spray the center hole. At the same time, the hollow column also plays a role in fixing the insulator body during the rising process.

[0030] 7. When the insulator body rises, the side spray assembly sprays half of the insulator body. The first motor starts, which can drive the fixed plate and the insulator body to rotate. After rotating half a circle, the other side of the insulator body corresponds to the side spray assembly, so that the side spray assembly can spray the entire outside of the insulator body, making the spraying more uniform and reducing the missed area.

[0031] When the spraying is completed, the side spray assembly rotates and resets. Due to the small rotation range, it will not affect the entanglement and obstruction of the connected glaze delivery pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The present invention provides Figures 1 to 8 A spraying and drying device for a porcelain insulator glaze is shown, comprising a spray box 1, both sides of which are connected to a drying channel 2, two conveyor belts 5 are arranged for transmission in the drying channel 2, the two conveyor belts 5 are distributed in parallel along the length direction of the drying channel 2, and the two conveyor belts 5 are of the same length and are used for conveying materials to be sprayed.

[0044] A plurality of support blocks 21 are fixed along the length direction on the outside of the two conveyor belts 5 . A V-shaped groove 36 is formed in the middle of the top of the plurality of support blocks 21 . The insulator bodies 13 are placed on the support blocks 21 adjacent to each other.

[0045] Support frames 4 are provided on the outer sides of both ends of the two conveyor belts 5. A connecting shaft is rotatably connected inside the support frame 4. Two gears 34 are sleeved on the outer side of the connecting shaft. The two gears 34 are respectively meshed with the inner sides of the corresponding conveyor belts 5. The inner sides of the conveyor belts 5 are provided with tooth patterns that mesh with the gears 34. The rotation of the two gears 34 can drive the conveyor belts 5 to rotate.

[0046] A connecting block is fixed between the two fixing blocks 6, a supporting leg 31 is fixed to the bottom end of the connecting block, a second motor 35 is fixed to one side of the supporting frame 4, and a driving shaft of the second motor 35 is fixedly connected to the connecting shaft.

[0047] In the actual operation of the invention, by starting the second motor 35, the second motor 35 drives the two conveyor belts 5 to transmit, thereby realizing the transportation of the placed insulator body 13. When the insulator body 13 is placed on the support block 21, it can have an anti-slip effect to prevent the insulator body 13 from sliding on the conveyor belt 5 when moving. At the same time, it can reduce the contact area of ​​the bottom end of the insulator body 13 and reduce the sticky area generated after spraying.

[0048] A spraying mechanism is arranged inside the spraying box 1;

[0049] A fixed block 6 is arranged along the length direction on the inner side of the two conveyor belts 5, and an L-shaped baffle 33 is fixed on the side of the two fixed blocks 6 away from each other, the two L-shaped baffles 33 are higher than the conveyor belt 5, and an air slot 32 is opened on the opposite side of the two L-shaped baffles 33, and the two air slots 32 are arranged above the conveyor belt 5. Air pumps 7 are fixed on both sides of the drying channel 2, and the two air pumps 7 are connected to air pipes 8, and the two air pipes 8 are respectively connected to the corresponding air slots 32;

[0050] It should be noted that the air groove 32 is opened in two sections along the length direction of the fixed block 6, that is, the two air grooves 32 are respectively located on both sides of the spray box 1. When the fixed block 6 is in the area of ​​the spray box 1, the air groove 32 is not opened to avoid the wind force affecting the spraying trajectory of the spray material during spraying.

[0051] In the actual operation of the present invention, when the insulator body 13 is placed on two conveyor belts 5 for transportation, the L-shaped baffles 33 can intercept both sides of the conveyor belts 5 to prevent the insulator body 13 from falling when moving. At the same time, the L-shaped baffles 33 can be used as wind ducts. The gas generated by the two air pumps 7 is discharged from the corresponding wind grooves 32. The two wind grooves 32 blow the insulator body 13 relative to each other to form a balance, so that the insulator body 13 can be in a centered position, avoiding contact friction between the side of the insulator body 13 and the L-shaped baffles 33, which affects the surface smoothness of the insulator body 13, as well as the subsequent spraying and aesthetics.

[0052] After the insulator body 13 is sprayed, the wind force output by the wind slot 32 can accelerate the drying and solidification speed of the glaze on the outside of the insulator body 13, while ensuring that the side of the insulator body 13 after spraying will not contact and stick to the L-shaped baffle 33, causing incomplete glaze.

[0053] The spraying mechanism includes an upper spraying assembly, a side spraying assembly and a lower spraying rotating assembly. The lower spraying rotating assembly is arranged below the side spraying assembly. The lower spraying rotating assembly is lifted and arranged in the spraying box 1, and the lower spraying rotating assembly is arranged below the conveyor belt 5. The upper spraying assembly, the side spraying assembly and the lower spraying rotating assembly are respectively used to spray the upper surface, the side surface and the lower surface of the insulator body 13.

[0054] The lower spray rotating assembly includes a fixed plate 22, both ends of the fixed plate 22 are fixed in the spray box 1, a second electric push rod 23 is fixed to the bottom end of the fixed plate 22, the telescopic end of the second electric push rod 23 extends out of the fixed plate 22, and a bracket 24 is fixed to the top of the extended end, the top of the bracket 24 is rotatably connected to a rotating shaft 26, a fixed disk 27 is fixed to the top of the rotating shaft 26, a protruding end is protruded in the middle of the top of the fixed disk 27, a first motor 25 is fixed inside the bracket 24, and the drive shaft of the first motor 25 is fixedly connected to the rotating shaft 26.

[0055] A plurality of nozzles 29 are arranged on the outer edge of the fixed disk 27, and the plurality of nozzles 29 are distributed around the center of the fixed disk 27. The spraying range of the plurality of nozzles 29 is a conical structure. The protruding end is arranged between the plurality of nozzles 29. A hollow column 28 is fixed on the top of the protruding end, and a plurality of spray holes are opened on the outside of the hollow column 28.

[0056] It should be noted that a cavity is provided inside the fixed disk 27, the bottom end of the fixed disk 27 is connected to a pipe, the pipe is connected to the glaze output mechanism, and multiple nozzles 29 are connected to the cavity of the fixed disk 27, and the pipe is a hose with a certain length.

[0057] When the insulator body 13 moves to the position of the lower spray rotating assembly, the second electric push rod 23 rises, driving the fixed disk 27 and the protruding end to extend upward until the protruding end contacts the bottom end of the insulator body 13, supports the insulator body 13, and drives the insulator body 13 to rise and separate from the support block 21. While the fixed disk 27 rises, multiple nozzles 29 are started to spray radial glaze upward, completing the spraying of the lower surface of the insulator body 13 before contacting the bottom end of the insulator body 13.

[0058] The hollow column 28 will be inserted into the central hole opened on the insulator body 13, and the glaze can be discharged from the spray hole to spray the center hole. At the same time, the hollow column 28 also plays a role in fixing the insulator body 13 during the rising process.

[0059] It should be noted that the center hole is where the steel cap is subsequently installed on the insulator body 13 .

[0060] A slide groove 12 is provided on one side of the two fixed blocks 6 away from each other, a U-shaped frame 11 is slidably arranged between the two slide grooves 12, and the side spray assembly is fixed on one side of the U-shaped frame 11. The side spray assembly includes a second support 19, and a second spray head 20 is arranged on the top of the second support 19. The second spray head 20 is higher than the conveyor belt 5, and the nozzle of the second spray head 20 and the side of the insulator body 13 are inclined at 45 degrees.

[0061] When the insulator body 13 rises, the side spray assembly sprays half of the insulator body 13, and the first motor 25 starts, which can drive the fixed plate 27 and the insulator body 13 to rotate. After rotating half a circle, the other side of the insulator body 13 corresponds to the side spray assembly, so that the side spray assembly can spray the entire outside of the insulator body 13, making the spraying more uniform and reducing the missed area.

[0062] When the spraying is completed, the side spray assembly rotates and resets. Due to the small rotation range, it will not affect the entanglement and obstruction of the connected glaze delivery pipe.

[0063] Since the bottom end of the insulator body 13 is supported by the support block 21, the support area cannot be sprayed by the downward spray rotating assembly, so V-shaped nozzles 30 are fixed on both sides of the bracket 24, and the contact surface between the bottom end of the insulator body 13 and the support block 21 corresponds to the spray outlet of the V-shaped nozzle 30. The V-shaped nozzle 30 is connected to the glaze through a pipeline, so that the glaze can be output from the V-shaped nozzle 30.

[0064] When the insulator body 13 rises, the bottom end of the insulator body 13 is separated from the support block 21, and the glaze sprayed from the V-shaped nozzle 30 contacts the unsprayed area at the bottom end of the insulator body 13, completing the entire spraying operation.

[0065] Specifically, an infrared sensor may be provided on the fixing plate 27 to monitor the position of the insulator body 13 , so as to precisely control the rise of the insulator body 13 .

[0066] In the actual operation of the present invention, the U-shaped frame 11 can slide outside the two fixed blocks 6, thereby driving the side spray assembly to move and changing the position of the side spray assembly.

[0067] The upper spray assembly includes a first support 17, the top of the first support 17 is fixed to the top of the spray box 1, the bottom of the first support 17 is fixed with a first spray head 18, the nozzle of the first spray head 18 is directly facing the upper surface of the corresponding insulator body 13, and a box door 3 is provided on one side of the spray box 1.

[0068] There is a spacing between the upper spray assembly and the side spray assembly, and connecting plates 15 are provided on both sides of the upper spray assembly. Both ends of the two connecting plates 15 are fixed to the inner wall of the spray box 1, and the first electric push rods 14 are fixed to the top of the two connecting plates 15. The telescopic ends of the two first electric push rods 14 extend out of the connecting plates 15, and a fixing box 38 is fixed to the bottom of the extended end, and an isolation plate 16 is fixed to the bottom of the fixed box 38. A rectangular air outlet 37 is opened at the bottom of the isolation plate 16 along the length direction, and a fan is fixed inside the fixed box 38. The air outlet direction of the fan is set downward, and the interior of the fixed box 38 is connected to the interior of the air outlet 37.

[0069] After the fan is started, wind is discharged from the air outlet 37 at the bottom end of the corresponding isolation plate 16 to form a vertical downward wind curtain. When the unpainted insulator body 13 passes through the first air outlet 37, the dust on the surface can be removed to avoid bulges. When the insulator body 13 between the two air outlets 37 is sprayed with glaze by the upper spraying assembly, the wind curtain generated by the two air outlets 37 can isolate the glaze from splashing and play a blocking role. Compared with the traditional baffle blocking, it will not adhere to the baffle. At the same time, the effect of wind can directly cause the excess glaze to drop into the collection box 10 at the bottom. When the insulator body 13 with the upper surface sprayed passes through the second air outlet 37, the effect of wind can accelerate the drying of the glaze.

[0070] In the actual operation of the present invention, when an insulator body 13 is being sprayed, the two first electric push rods 14 are started to descend, which can not only avoid collision between the insulator bodies 13, but also isolate the insulator body 13 being sprayed to avoid affecting the subsequent unsprayed insulator body 13 and causing the problem of over-spraying.

[0071] A collecting tank 9 is provided at the bottom of the spray box 1 , and a collecting box 10 is connected to the bottom of the collecting tank 9 . An electric heating tube is fixed inside one of the drying channels 2 .

[0072] Excess spray material will fall into the interior of the collection box 10 through the collection groove 9. When the spraying is completed, the insulator body 13 after the spraying can be dried by starting the electric heating tube, and the glaze can be shaped and dried.

[0073] The present invention also discloses a spraying and drying processing method for porcelain insulator glaze, comprising the following steps:

[0074] S1, placing multiple insulator bodies 13 at equal distances on the conveyor belt 5 for conveying, and the bottom ends of the insulator bodies 13 are supported by the support blocks 21 of the conveyor belt 5 to reduce the contact area;

[0075] S2, start the air pump 7, so that the two air slots 32 blow the insulator body 13 being transported relative to each other;

[0076] S3, the insulator body 13 transported into the spray box 1 passes through the isolation plate 16 and performs dust removal;

[0077] S4, the insulator body 13 passes through the upper spraying assembly and the lower spraying rotating assembly in sequence, the lower spraying rotating assembly rises and drives the insulator body 13 to rise and rotate, and spraying is performed on the lower surface and the side at the same time, and drying is performed after the spraying is completed.
